On: AMD's Turin: 5th Gen EPYC Launched

700+ threads over 2 cores, can saturate 2 400gbe Nic's 500 wats per chip (less than 2 wats per thread)... All of that in a 2U package.... 20 years ago that would have been racks of gear.

I think those really 2 watts per thread are a lot more important than what us home users usually think. Having to deliver less power and having to dissipate less watts in form of heat in a data centre are really good news to its operative costs, which is usually a lot bigger than the cost of the purchase of the servers

With these CPUs one can definitely hit much higher rates.

800Gbps from a single server was achieved by Netflix on much lesser systems two years ago:

If I were to guess, this hardware can do double that, also helping that we now have actual 800Gbps Ethernet hardware.

Indeed 20 years ago this would have been racks of gear at a very high cost and a huge power bill.

That's one hell of a pixelflut server.

> 700+ threads over 2 cores

I assume you mean 2 sockets.
